Keyline is ordered set of principles,
techniques and systems. When fully utilised Keyline Designs produces
strategies and taticcs to develop the natural or existing landscape
through regeneration and enhancement.

On Keyline properties the typical vistas are of lakes
with water birds, roads along the contours and ridge lines, contour
tree belts, healthy crops and green pasture growing in dark
biologically fertile soil.

Keyline Designs is a consulting service providing assessments and plans
for the sustainable development of land and water resources in
agricultural and suburban areas.

Kindle books can be read nearly all computers, touchpads and
smartphones.
The reader software is free and downloadable from Amazon UK. Ctrl+

KEYLINE - MORE ABOUT WHAT IT IS...

Keyline is a set of principles, techniques and systems, which
form the logical basis for a practical plan for the sustainable
development of rural and urban landscapes.

The first book on Keyline book was published in 1954. In it, P.A.
Yeomans exploded the myth that it takes 1,000 years to produce an
inch of topsoil. Yeomans pioneered, among other things, the use of
on farm irrigation dams in Australian, as well as chisel plows and
subsoil aerating rippers. Yeomans perfected a system of amplified
contour ripping that controlled rainfall run off and enabled the
fast flood irrigation of undulating land with out the need for
terracing.

Although Keyline was initially developed for rural property
planning and is superb Landcare it also provides a basis
for more sustainable suburban planning and larger subdivisions.
Keyline Designs features large earth walled irrigation dams
that are all equiped with through-the-wall Lockpipe systems to
gravity feed irrigation stock water and yard water. Across the
landscape the dams may be interlinked by channels. Graded
earth channels broaden the catchment areas of high dams,
conserve the height of water and transfer rainfall run-off into
the most efficient high dam sites. Flat land flood irrigation
at up to sixteen hectares per hour and flood irrigation of
undulating grass land. The road systems of Keyline
follow both ridge lines and the graded contour water channels.
Contour roads and paths, being almost flat, provide easy low
energy movement across even very undulating land.

Avenues of trees are left or planted parallel to the
roads and channels and as well as in tiered contoured forests.
Better building sites become revealed and then fences and gateways
can be positioned more strategically. Within this harmonious
design, soil regeneration can occur by deepening the
bio-fertility of the topsoil and converting subsoil
into living topsoil. This is achieved partially by soil
aeration, which increases water absorption, also by an amplified
contour cultivation pattern, which prevents soil wash and
by using an enhanced cell grazing design for "rational"
grazing. Incidental results are the healing of soil erosion
and salinity and better stock health.

In a rural setting Keyline is far more than a unique combination
of water conservation and farming with nature.
Keyline completely supersedes the widely imposed but misconceived
concept of Soil Conservation. One of the typical benefits of
Keyline is the rapid development of living soil.

When Keyline Design is applied to urban design the contour roads
will assist low energy transport. Water storage within the
suburban area will be both picturesque and provide a readily
available supply of "yard" water for irrigation of suburban
gardens and park. It was back in the 1970's that the
originator of Keyline, the late P. A. Yeomans proposed the use of
Keyline methods to create City Forests for sewage effluent
utilisation.

“Our soils have progressed incredibly fast, of course!
In 2008 we saw 9” deep topsoil profiles become 17” + in a single
growing season.
Astounding to even to me with my optimism.” Abe Collins, Vermont

" I read a copy of "Water for Every Farm". I think it's
brilliant. The best solution I have read to supply all our water
needs. As I have a background in geology and interest in
perma-culture, quassi-biodymanics (anything organic), I visualise
a holistic approach to sustainable land use and care…"

called:

Well-designed landscapes are beautiful and highly productive. In
Australia and elsewhere Keyline Designs brings the order of
permanence into decision making for rural land design.

Increased profits come from reduced production costs and
increased productivity. This is done most efficiently in a
landscape specifically designed to achieve this result.

The application of Keyline Designs results in a custom made
property plan. Keyline reveals the potential as well as developing
the unique features of each property. Keyline plans for optimised
farm water utilisation and improving soil fertility.(Click here for: Keyline consulting
information)Your Keyline Designs consultant will reveal the Keyline
potential of your property.

Land planning is facilitated by contoured maps. When these
contour maps overlay rectified (true-to-scale) aerial photograph,
more comprehensive planning can be achieved. It is a good
investment to obtain a contoured aerial photograph of
your land. These photo-maps can also be produced in a digital
format.

AERIAL PHOTOGRAPHS with NEW CONTOUR LINES

Keyline Designs can simplify property planning by supplying large
scale, contoured, aerial photographs. These orthophoto contour maps
are the perfect basis for planning property development. They can
reveal, especially to the experienced eye of your Keyline
consultant, valuable information about the development potential of
your land. They can reveal the best locations for fences, roads,
irrigation dams and channels, contour banks, building sites and tree
lines. These contoured orthophoto maps reveal development potential
and enable better cost estimations than are otherwise possible.

Properties currently covered by departmental topographic maps
showing only ten metre contour intervals, can be re-mapped onto
existing aerial photo stocks with new form line contours at two
metre intervals.

An orthophoto map is derived from a three-dimensional image of
the area. This image is created by scanning overlapping pairs of
aerial photographs into a specialised computer. It is possible to
calculate the height of any point by comparing the overlapping
images. A finely spaced survey grid is draped over selected areas
within this virtual model of the landscape. Computer analysis
enables the height of each point on the grid to be discovered and
using this data the new contour lines are then drawn. Prior to
printing the aerial photograph is rectified to a true scale so as
to match the contours and property boundaries.
The matching digital data is also be available on CD. With
suitable software it is possible to view the property as a three
dimensional, digital terrain models (DTM).

Here is part of Email from one client who said in Oct 1998 ...

Dear Ken

Thanks for your BRILLIANT ortho map of my property. It looks
fantastic. I have just received it but have not yet got the CD.
Hope it will arrive soon.

I can tell you that the negotiations re the neighbours’s farm
are entering the middle stages and if they go in my favour, I
shall certainly be calling on you for assistance.

Dont worry about the CD as a letter can take a full month to get
across Johannesburg. It will get here eventually.
Regards
